Try this: string requestURL = "Yourapiurl?name='test'&Id=123&departid=456" ; HttpWebResponse webResponse; StreamReader sr = null ; string returnResponseText = string .Empty; HttpWebRequest request = (HttpWebRequest)WebRequest.Create(requestURL); request.Headers.Add( "your header key" , "value of key" ); request.Accept = "application/json" ; request.Method = "PUT" ; request.ContentType = "application/json" ; List modelllist= new List //bind data to modellist var data = Newtonsoft.Json.JsonConvert.SerializeObject(modelllist); byte [] bytes = Encoding.ASCII.GetBytes(data); request.ContentLength = bytes.Length; using (var stream = request.GetRequestStream()) { stream.Write(bytes, 0, bytes.Length); } webResponse = (HttpWebResponse)request.GetResponse(); sr = new StreamReader(webResponse.GetResponseStream()); returnResponseText = sr.ReadToEnd();
